        //1.通过function 关键字声明
        function play(){
            console.log('今晚吃鸡');

        }play();


        //2.匿名函数（把函数赋值给了变量）
        let eat  =function (menu) {
            console.log('今晚吃'+ menu);
        }
        eat ('红烧鱼');


        //3.箭头函数
        let  run =()=> {
            console.log('就这么跑来跑去');
        }

        run();
